Associated rock type; With what rock type and/or other minerals is this mineral found? Degree of metamorphism and alteration; Mineral shape, properties or form been altered. Lattice structure and geochemistry; Signature chemical elements and bonds of the mineral. For example, is the mineral hydrous like mica or non hydrous like Jadeite.
Specific gravity, streak (streak color and mineral hardness) and X-ray powder diffraction are quite specific for a Nickel-Strunz identifier (updated 9th ed.). Nowadays, non-destructive electron microprobe analysis is used to get the empirical formula of a mineral.
A United States Navy Aviation boatswain's mate tests the specific gravity of JP-5 fuel. Relative density, also called specific gravity, [1] [2] is a dimensionless quantity defined as the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material.
It is usual for hydrometers to be used with dense liquids to have the mark 1.000 (for water) near the top of the stem, and those for use with lighter liquids to have 1.000 near the bottom. In many industries a set of hydrometers is used (1.0–0.95, 0.95–.) to have instruments covering the range of specific gravities that may be encountered.
In homebrewing, a brewing refractometer is used to measure the specific gravity before fermentation to determine the amount of fermentable sugars which will potentially be converted to alcohol. Brix refractometers are often used by hobbyists for making preserves including jams, marmalades and honey.
It is an important rock-forming mineral in low- to medium-grade metamorphic rock formed by metamorphism of mafic or pelitic rock. [9] It is also common in igneous rocks, usually as a secondary mineral, formed by alteration of mafic minerals such as biotite , hornblende , pyroxene , or garnet . [ 10 ]
